Nope - boot from the CD and use format to label the disk.

1. Corrupt Label : Wrong Magic Number

Hi,
   My problem is that I have a 9.1G seagate drive on a Ultra 10 is and
it keeps saying ...

# fsck -F ufs /dev/rdsk/c0t0d0s2
** /dev/rdsk/c0t0d0s2
BAD SUPER BLOCK: MAGIC NUMBER WRONG
USE AN ALTERNATE SUPER-BLOCK TO SUPPLY NEEDED INFORMATION;
eg. fsck [-F ufs] -o b=# [special ...]
where # is the alternate super block. SEE fsck_ufs(1M).

and I can't run the format command in the format program because it says
I must use "Manufacturer supplied Format utility" which I don't have and
don't know how to get.  But I have tried the following ...

1. I have tried to use format to create a new label and  and still
"corrupt label : wrong magic number"  error.

2. I have tried restore a backup label and still "corrupt label  : wrong
magic number"  error.

3. I have also tried "fsck -o b=32"  and and still "corrupt label :
wrong magic number"  error.
